FEED-TABLE FOR ROLLING-MILLS.

Specification of Letters Patent.

Patented June 18, 1907 Application filed February 3,1905. Serial No.244.020.

To all whom it may cancer-1o;

Be it known that I, SIGMUND V. HUBER,

gheny and State of Pennsylvania, a citizen of the United States, haveinvented or discovered certain new and useful Improvements inFeed-Tables for Rollingdvlills, of which improvements the following is aspecification.

In operating three high mills it is frequently desirable that the pieceshould pass back and forth through the same passes, z. e. p or moretimes and it is u per and lower, two

a so desirable in some cases that in lieuof feeding the articletransversely to the next adjacent pass to skip one or more passes and tofeedv the article into the second or third In Letters Patent No. 1February 9th, 1904, I

pass along the rolls. 751,733 granted to me have described and claimedcertain improvements in feed mechanisms for mills in which a transversemovement of the article on the feed table is effected by means operativeby the feed table itself in its vertical movement. In this patent noprovision is made whereby an article can be passed several times throughpasses in the same vertical plane or whereby the article may be shiftedfrom one pafis to the second or third pass along the ro s.

The invention described herein has for its object a construction ofmechanism for the transverse shifting of the articles onthe tables soconstructed and arranged that the article may remain on the tablewithout lateral' movement during the vertical movements of the table ormay be shifted to any desired extent transversely with the table duringthe movement of the latter.

The invention is hereinafter more fully described and-claimed In theaccompanying drawings forming a part of this specification Figure 1 is atop plan view of a feed table having my improvements applied thereto.Fig. 2 is an end elevation of the same. Fig. 3 is a sectional detailedview, the plane of section being indicated by the line IIIIII Fig. 1.Fig. 4 is a sectional detailed view on a plane indicated by the lineIVIV Fig. 3. Fig. 5'is a view partly in elevation and partly in sectionillus-- trating a modification of my improvement. Figs. 6 and 7 arediagrammatic views show ing passes in rolls and the movements of thearticle on the feed tables in connection with said passes.

In the practice of my in'vention the feed table is arranged to movevertically either as a whole or at. one end. In the construction shownthe whole table is designed to move vertically in suitable guides 1 and2. The

guides 1 at the rear end'of the table being constructed to'prevent boththe lateral and longitudinal movement of the table while the guides 2,which are generally secured to the housings of the rolls, are adapted toprevent the lateral movement of the table.

driven feed rollers 3o perated in any suitable manner such for exampleas an electric motor 4 connected by a suitable train of gearing to alongitudinal shaft 5, rovided with beveled gears intermeshing withcorrespondingly shaped gears on the feed rollers. Any suitable means maybe employed for raising and lowering the table, such for example as thatshown consisting of shafts 6 provided with arms 7 connected to the tableby adjustable pitmen '8. These: shafts are also provided with arms 9,connected as shown to a fluid pressure cylinder 10. By the operation ofthis fluid pressure cylinder the shafts are rotated and the desiredvertical movement is imparted to the table. In order to shift thearticles laterally across the table, ribs or guide plates 11 areadjustably secured to slides 12 which are mounted in suitable guideways13, as clearly shown in Figs. 1 and 4 arranged transverselyof the table.The adjustability of the ribs can be attained in any suitable manner, asfor example by slotting the slides 12 and securing the ribs to theslides by bolts passing through the slots.

' The slides 12 are connected by rods 14 to arms 15 on a shaft 16, andto this shaft is also secured another arm 17 which has an adjustableconnection to a stationary abutment, as shown in Figs. 2 and 5. In Fig.2 the connection of this arm 17 tov the abutment 18 is formed bythreaded rods and turnbuckle 19, such connection having its endspivotally connected to the slide 20 on the arm 17, and to a movable link21, provided with an angular slot for the reception of, the abutment1.8. It will be readily understood that when the abutment is in thehorizontal portion of the slot in the link, a vertical movement of thetable will cause a rotation of the shaft 16 and a consequent shifting ofthe slides 13, as the shaft is carried by the table but the arm 17thereon is prevented from movement and hence a rotation of the shaft iseffected. By adjusting the length of The table is provided with a seriesof positively a screw operated by a hand-wheel as shown,

' duced movement of the block along the arm any desired transversemovement of the slides will be efiected by the regular vertical movementof the table. The link 21 is shifted on the abutment 18, by a lever 22connected to the link by a rod 23. If no transverse movement of theslides is de sired as when the piece being rolled is to be fed back andforth through the same passes as a in Fig. 7 a number of times, the linkis shifted so that the abutment will lie in the vertical portionthereof. When the abutment is in this position and the table is movedvertically, the link will slide up and down along the abutment and nomovement will be imparted to the shaft or the slides.

In lieu of the construction shown in Fig. 2, that shown in Fig. 5 may beemployed. In this construction a block 24 is pivotally connected to theend of the arm 17 and arranged to move in guides along a swinging arm orlink 25. This arm or link 25 is pivoted as shown at its lower end to astationary part or abutment of the machine and connected to an operatinglever 22 by a rod 23. When the arm or link is in the position shown nomovement will be imparted to the slides 12, on the vertical movement ofthe table, but if the arm or link be shifted to the right averticalmovement'of the table will cause such realong the link as to impart thedesired transverse movements of the slides 12. I

It is some times desirable as before stated to skip one or more passesalong the rolls, and hence provision must be made for a greater movementof some of the guide ribs than of the others. To this end the slides 12are made in sections as clearly shown in Figs. 2 and 3. When the orderlymovement of the articles from pass to pass is desired as illustrated inthe diagrammatic view Fig. 7 these sections or series of slides areconnected by a link 27 in such manner that both sections will be movedtogether. If however it is desired that some of the articles beingrolled shall be moved a greater distance transversely than otherarticles at the same time passing through the mill, the main sections 12are connected to the other sections 12 in such manner that the mainsections will have a considerable movement independent of the sections12*. A desirable construction to this end consists in connecting the twosections by means of links 28, having slots therein of a length equal tothe distance which it is desired that the main section shall moveindependent of the sections 12", as shown in Fig. 3. en thus connectedthe section would have transverse movements such as indicated in Fig. 6,the sections 13 moving transversely from the planes of passes a to planeof passes b, whereas the sections 12 will move from the plane of passesb to the plane of passes d, skipping passes c.

It is characteristic of my improvement that by shifting a part or memberof the connection from the table to the abutment, as the part or member21 or 25, the guides on the table will either remain stationary or movetransversely of the table when the latter is moved up and down. Andfurther it is characteristic of the construction shown in Fig. 5 thatthe movement of the guides transverse of the table can be varied at anytime without varying the vertical movement of the table.
